MAGAZINE WRENCH.

Application filed Decembertl, 1824:.v Serial No. 758,075.

The present invention provides a tool of the nature of a spanner or nutwrench which embodies provision for receiving a cap screw or a pluralityof nuts and which is of special advanta when changing pneumatic tires orper orming other work requiring the loosening and ti htening of a numberof nuts, screws and olts.

Other objects and advantages will be apparent and suggest themselvesasethe nature of the invention is understood. v 1

While the drawings illustrate. an embodiment of the invention it is tobe understood that in adapting the same to meet different conditions andrequirements, various changes in the form, proportion and minor detailsof construction may be resorted to without departing from thenature ofthe invention.

Referring to the accompanying drawings forming a part of thespecification,

Figure 1 is a side view of the preferred form of tool, the pressurepiece being in section Figure 2 is an end view of the holder for thebolts and nuts, showing a portion of the brace,

Figure 3 is an enlarged longitudinal sectional view of the nut and boltholder having a portion of the brace attached,

Figure 4 is an enlarged sectional view on the line 4-4c of Figure 1, and

Figure 5 is an enlarged sectional View on the line 5-5 of Figure 1.

Corresponding and like parts are referred to in the followingdescription and designated in the several views of the drawings by likereference characters,

The numeral designates the holder for the nuts, bolts, screws, and thelike, the same being tubular and constituting a magazine, and forconvenience of operation an ordinar brace 11 is attached at one end toan en of the holder 10, the latter being closed at one end by means of aplug 12 through which and the holder passes an end of the brace 11 whichis made secure by means of a rivet or pin 13. The outer or working endof the holder 10 is reinforced by means of a ferrule or band 14 whichhas a portion cut away as indicated at 15 toreceive a spring 16 whichnormally exerts a pressure upon a retainer 17 to hold it projected intothe ball or opening of the holder 10 to prevent outward displacement ofthe nuts, bolts or screws placed within the holder or received thereinwhen removed from the cooperating part, thereby obviating the necessityof receivin the same inthe hand which is objectiona le, particularlywhen changing tires or performing other work when it is desired not ,to.soil the hands. The retainer 17 preferablyfconsists of aball.

A release 18 is disposed-at one side of the holder 10vand is mounted inthe ferrule or band 14 and islprovided at one end with a crank and'at'the opposite end with a lift 19 whichris disposed beneath the freeend of the spring 16 so that when the crankof the release is movedoutwardly, the free end of the spring 16 is correspondingly thrownoutward thereby relieving the retainer 17 of inner pressure so that thenuts,

screws, or the, like contained within the holder may readily discharge.The crank portion of'the release normally lies against the side of theholder thereby preventing accidental operation thereof or injury theretoby striking an object.

It will be understood that the release 18 is to be used only when itis-desired to emp-" capacity to hold all of the nuts in an un-- screwlngoperation, as for instance in removing the head bolts of an internalcombustion engine. In screwing on nuts from the magazine it will beapparent that the bolt end will engage with the first nut in themagazine and will be pulled down as the nut is screwed down on the boltand the wrench will be self releasing.

A follower '20 is located within the holder 10 and is normally pressedoutwardl by means of a coil spring 21 which is sol ered or otherwiseattached at its inner end to the plug 12 and at its outer end to thefollower and this spring normally urges the discharge of an articlecontained within the holder, casual displacement of such article beinprevented by the retainer 17, but whic yields to admit of entrance orremoval of the article by the application of sufficient force thereto,

What is claimed is A device of the class described comprising a magazinehaving an opening through the side thereof to its holdmg chamber, aretainer for the lowermost article in said chamber occupying saidopening, a contractile spring surrounding the chamber having a springdisplacing element located and being in contact with the retainer tointermediate a portion of the spring and hold it in place and permityielding therethe exterior of the magazine. 10 of, said magazine havinga band surround- In testimony whereof I afiix my signaing the same, saidband having a recess acture.

commodating said s ring, and a release member carried by said band, saidmember CLYDE R. WORK.
